Description

The Locked Cube Mechanical Puzzle has a distinct interlocking design that truly stands out amongst other puzzles in the same genre. The cube is designed by Belgian puzzle maker Ronald Kint-Bruynseel, and is made up of 6 wooden pieces and one wooden cube. To begin, the first goal is to unlock the puzzle and free the cube. Then, the puzzler must configure the puzzle back into the same shape - with the cube inside! Be warned, just because you’ve dismantled the mechanism does not make it easier to put back together! However, with enough trial and error and a patient demeanor, success is inevitable.


This puzzle makes a great gift for friends, or even a stress-relieving fidget toy for your desk. The possibilities are endless!
